Lowthers midrange: how do they compare?

I realize Lowthers aren't very popular here. A quick search returned threads from 10 years ago, and 3 from 2012/2013 asking for pointers to repairs...

Still I'd like to try and ask since my question isn't geared at them being used as fullrangers but instead as midranges. How do they sound compared to the better dedicated midarnges you have heard? I'm thinking of using them in an active system, from 300 to 2000Hz (where I understand they cross to their wheezer cone).

Their sensitivity and 15 ohm impedance is great for SETs. Their price is very high compared to most midranges so not a trivial decission. The "Lowther shout" seems to be above 2kHz. I read they are very fast and detailed, dynamic, and able to retrieve details buried in the music, all while being musical. But would like to hear from anybody who has experienced them.

Thank you!

Indeed, I want a midrange. Sure I haven't gone into explaining goals as not many DIYs come here. But saying I'm building an active system, midrange driven by a 2A3 SET, and running 300 to 2000Hz...should tell an experienced builder quite a lot. And I've also focused on direct radiators.

So what are the better options, suited for 2A3 amps? Sensitivity of 97+ dB at 2.83V, at least 12 ohm drivers naturally preferred.

So far have not come across such a midrange. Some pro drivers get close, but their 300 or 400W ratings...make me wonder. MTM with midranges in series could do it. If fact something I will be experimenting with to better understand the audibility of lobbing (caused by a very large AMT tweeter).

 Run a compression driver as a mid.                                                         Or a  http://www.usspeaker.com/beyma%20tpl1200h-1.htm for a 2 way   
 Also a SEAS x2 does most of what you ask and mates well with RAAL ribbons and Mundorf AMT. Honestly I think you should rethink most all of what your trying to do. K.I.S.S. is best in loudspeaker design. A tri amped dissimilar driver different radiation pattern loudspeaker will be a can of worms.

That Beyma tweeter is a great idea. So much so that's the tweeter I'very chosen. Actually it's the TPL150H instead of the 200. That is why the Seas aren't a good match: their sensitivity is way too low compared with the 102dB of the TPL vs 85dB for the Seas. Otherwise they would be great.
